A practical method to synthesize α‐alkylated arylacetonitriles from arylacetonitriles and alcohols without using any expensive transition metal complexes is demonstrated here. Following this base‐catalysed sustainable procedure, various arylacetonitriles were successfully alkylated with different alcohols. The practical applicability of this protocol was extended by one‐pot synthesis of important carboxylic
We achieved chemoselective synthesis of α-alkylated arylacetonitriles and acetamides by combining Ir complex-catalysed direct coupling of alcohols and nitriles by a simple adjustment of the base. Methanol and ethanol performed well as the alkylating reagents. This method of acetonitrile alkylation provided a novel approach for carbon chain extension.
我们通过简单的碱调节,结合 Ir 络合物催化的醇和腈的直接偶联,实现了 α-烷基化芳基乙腈和乙酰胺的化学选择性合成。甲醇和乙醇作为烷基化试剂表现良好。这种乙腈烷基化方法为碳链延长提供了一种新方法。
